Notes. Parameters include the black hole spin (a∗), the spot orbital period (P), observer’s inclination angle (i) which is the angle between the observer’s line of sight and the black hole spin axis, position angle of the black hole spin axis on the sky (PA, note that Doeleman et al. 2009b defined PA as a disk major axis position angle, i.e., their PA is offset by + 90° from our values), observing frequency (ν), ADAF flux (Disk), minimum and maximum fluxes (Min and Max), electron number density (), electron temperature (), gas-to-magnetic-field-pressure parameter (β), the spot orbital radius (rspot), and the spot electron density ().
